Morse (Raspberry Pico)

Example of the serial port communication.

This project allows you to input a word or sentence using Raspberry usb serial port via the Minicom terminal, convert it to Morse code, and blink an LED on a Raspberry Pi Pico to represent the Morse code. The Morse code translation is also printed back to the terminal.

Building the Project

1. Clone the Repository:

   $ git clone https://github.com/L-A-Marchetti/Morse.git
   $ cd Morse

2. Clone the pico-sdk

   $ cd ..
   $ git clone https://github.com/raspberrypi/pico-sdk.git --branch master
   $ cd pico-sdk
   $ git submodule update --init

3. Copy the external pico sdk import

   Copy ‘pico_sdk_import.cmake’ file from the /pico-sdk/external directory into the github repository.

   $ cd ../Morse
   $ cp ../pico-sdk/external/pico_sdk_import.cmake .

4. Create the build folder

   $ mkdir build
   $ cd build
   $ export PICO_SDK_PATH=../../pico-sdk
   $ cmake ..

5. Compile (if needed):

   make -j4

6. Upload the Code to the Pico:

   Connect your Raspberry Pi Pico to your computer via USB, then drag and drop the generated morse.uf2 file from the build directory to the Pico.

Running the Program

1. Open Minicom:

   sudo minicom -b 115200 -o -D /dev/ttyACM0

2. Interact with the Program:

   • Enter a word or sentence.
   • End the input with !.
   • The program will process the input and start blinking the LED according to the Morse code translation.
   • The Morse code translation will also be displayed in the Minicom terminal.
